What are the observation methods of Ryutsuki and Liu Ri?

In the year of Universiade, Ryutsuki's floating days formed a new four-column analysis to see what the five elements were in power. Whether the five elements are good or bad for the initial fate is generally more specific. For example, the influence of fleeting time in this year is greater than that of the Universiade.

That is more troublesome to analyze. Generally, it can be done until the flight time.
